VIDEO: Iggy Azalea and Britney Spears Go Totally '80s for "Pretty Girls"

Iggy Azalea is out of this world -- literally -- in her new music video with Britney Spears.

"Iggy Igg"s stars as an alien set on having a good time in the video, with Spears playing the part of her glammed up tour guide.

Azalea crash-lands in Spears' pool in the video, and Britney, unfazed by the invasion, dresses up her new guest in totally '80s attire and takes her out on the town. At one point, the two show off their Valley Girl impressions before moving on to a club.

The song collaboration debuted last week, and Azalea and Spears will make their live performance debut during the Billboard Music Awards on Sundayat 8/7c on ABC.
